Same fan failure issue on 7200

Fan failure 4 blinking lights on mine as well. Interesting though, It's only with the HD output from my cable box. My Blu-Ray movies play just fine in HD with no fan failure. Both are running RGB connectiond (I think). Input 3 and 6.

Do the fans work? they may need to speed up at certain times for cooling reasons (different signals may need more power. more power, more heat). if the fans aren't working up to par, you may need to clean them or replace them. use canned air.

My brother has a 60" Sony xbr1 year 2006 and the red light blinks when you turn on but no picture or sound. Has a brand new bulb, that's not the issue.


Could be a cooling fan. Sometimes they don't start because of dust buildup. Could be worn out also. I had to replace mine once. Can order via internet.

The Casablanca 88U33M Scandia Ceiling Fan only has three wires, a black, a white, and a green wire (ground). How do you wire the fan and light on seperate switches?


If you want to control both the light and the fan using 3-ways, then just wire 2 sets of the 3-way circuits. For this you need two sets of 3-wire between the switches, and one 3-wire cable from the switch location to the fan/light box.

At box #1 (a 2 gang box), you will run a power cable (marked cable #1) into it. From there you run 2 sets of 3-wire cables (identified as cable #2 & cable #3) to the other switch location, which will also be a 2-gang box (box #2).

Also from box #1, you will run a 3-wire cable (cable #4) to the fan/light box (box #3).

Hook up is as follows:

Box #3: connect black of cable #4 to black (fan), connect red of cable #4 to blue (light), connect white of cable #4 to white (fan/light), and connect the bare to the green.

Box #2: Connect white of cable #2 to identified terminal on 1st 3-way switch (#3). Connect red & black of cable #2 to the remaining screws of 3-way switch #3. Next connect white of cable #3 to identified terminal of 2nd 3-way switch (#4), and connect black and red to remaining screws. Tie all grounds together and terminate to both switches.

At box #1, connect black from cable #1 to whites in cables #2 & #3, using a wirenut. Connect white in cable #1 to white in cable #4. Connect black and red in cable #2 to 3rd 3-way switch (#1) and connect black and red in cable #3 to 4th 3-way switch (#2). Connect black in cable #4 to identified terminal of 3-way switch #1, and connect red in cable #4 to identified terminal on 3-way switch #2. Tie all grounds together and to the switches

Dual Dimmer / lights go off when fan not on high.


I'm not sure of the exact wire arrangement, but it appears as though a fan and light wire are mixed up, as thought the lights are feeding off the fan wire. Its possible that in the switch box or even in the fan box the output of your fan is tied to the lights so that when the fan is at it's highest output (maximum current), yours lights work properly and not at any other setting. Check wiring for errors.

Infocus screenplay 7200 fan failure with new lamp After powering on, red LED blinks 4 times which means fan failure of the fan that is part of the lamp module. Already returned initial new lamp and got...


Not sure if this helps with the 7200 bu had a 4805 with a failed fan issue. There are two fans inthe unit, one smaller one that cools the color (colour) wheel and the larger one that cools the lamp. This unit had a problem with the larger lamp fan not turning. Unplugged and disassembled the unit to get the fan out and tested the fan using a 9v battery and a couple of wires (best to uplug the fan from the controller board so you are not forcing voltage into the unpowered controller board... that said, I did it hooked up just peeling back the label in the centre of the fan and touching the wires to the solder contacts) The fan worked fine so figured the controller board was the issue, so this wasn't going to be a simple "buy a new fan" issue.

Here is where your mileage may vary...

I decided that it would be OK to just run the fan. Unplugged the fan and powered it from the 9V battery and assembled the unit and powered it up. Found that there was 7v available on the power board at the second pin that was alwasy on when the power switch was on (thats the positive 7 V pin, but measure it with a meter since we are talking about a different projector) and just wired the fan direct to pin 1 and 2 (1 is ground on the 4805, 2 is +7V) and so now whenever the main power is on the fan runs, so after ti cools down I just power off the main power when not in use... or let the fan run if the noise isn't an issue. Crude but effective fix.

5 mostly green verticle lines on all digitle channels. HD ok.


I just called customer support and my issue is now fixed, to my extreme surprise.

It sounds silly (and a tad embarrassing), but here's what I did:

1) Unplug the TV
2) Wait 30s
3) Plug the TV in
4) Test

Apparently even if the TV is "off" for a few days it never fully shuts down unless the power is unplugged. Not sure if this will help anyone else, but I had the exact same problem others are describing. Good luck!
